Images: incorrect extension

+3 votes
On trying to upload images, I now keep getting "this image Is corrupt or has an incorrect extension. Please check the file and upload again." This is new. My habit is to point the iPad at the image, click it and upload. No change in file type (whatever that is; I imagine jpg). What should I do please?

On the Mac (Apple products, iOS, iPad, etc.), file extensions aren't necessary to identify the type of a file. For Windows (Microsoft products), its still necessary, though usually hidden these days. A file extension is historically a dot and three letters tacked onto the end of the filename.

For most websites that support uploading and processing files of any type, its much simpler to identify the type of file by examining its file extension (if it has one). Very few websites have the necessary, and more complicated code to do so without it.

Although I use a Mac myself, I'm personally unfamiliar with the iPad specifically. I don't know if you have the ability to rename a file and give it an extension, if it doesn't already have one.

Once again, I'm so glad you're helping with questions like this, Dennis. This is a much better answer than I could have given!

and yet... no gold star :)


edit: thanks Jerry :)
I expect I could provide a new extension but I think it should be vastly less complicated than that and I ought to be able to upload directly.
to make computer systems less complicated for us end-users, is extremely complicated for software developers (who often take shortcuts when there are acceptable workarounds). :)
